Network Rail has issued a significant pipeline notice announcing the forthcoming procurement of Track Focused Railway Systems Contracts, aimed at delivering track renewals, upgrades and associated infrastructure works across the UK rail network during Control Periods 8 and 9 (CP8 and CP9).
The estimated total value of the contract is an impressive £5bn before VAT (£6bn with VAT), reflecting the scale and complexity of the work planned for the next decade.
The contract forms part of the Rail Systems Alliances framework, longstanding partnerships between Network Rail and industry suppliers tasked with designing and constructing track works on the plain line and switches and crossings (points).
The scope of the upcoming Rail Systems Alliances framework extends beyond track laying to encompass a comprehensive suite of services including survey, site investigation, design development and installation activities. This also covers drainage, formation, ballast, sleepers, slab and rail installations, as well as associated traction power, signalling and minor civil engineering projects such as foundation works for signal and traction power equipment, level crossings, platform works and the construction of cable troughing routes.
Existing Rail Systems Alliances
- Central Rail Systems Alliance: Network Rail, Balfour Beatty, AtkinsRéalis and TSO
- South Rail Systems Alliance: Network Rail, Colas and Aecom
- Scotland Rail Systems Alliance: Network Rail, Babcock and Arcadis
Existing alliance partnerships are scheduled to conclude between May and June 2029. To ensure continuity and progression, Network Rail is seeking to appoint new suppliers to commence mobilisation by mid-2028, with the contract going live in mid-2029. This procurement milestone marks a critical phase in maintaining and enhancing the UK’s rail infrastructure amid increasing travel demand and a strategic push towards sustainability.
The scope for the next contract includes key priorities such as track renewals and upgrades across designated routes, integration of works with electrification and signalling programmes, and the provision of specialist plant and equipment to support efficient delivery. Notably, the contract will encompass adherence to the requirements arising from the transition to the Great British Railways (GBR) model, as well as sustainability objectives aligned with environmental commitments.
Network Rail has emphasised its intent to maintain a collaborative approach during the procurement process, signalling proactive market engagement in the months ahead. Detailed scope documents and the commercial model are anticipated to be published alongside the tender notice, which is set for release on 4 May 2027, providing suppliers with essential guidance to prepare competitive bids.
With contract dates projected from 1 August 2028 through to 31 July 2039, this agreement represents a long-term investment in the UK’s rail infrastructure, reflecting Network Rail’s commitment to delivering a safer, more reliable, and future-ready railway. The scale of investment underscores the critical importance of track and associated systems renewals as central to the government’s broader transport strategy, linking infrastructure resilience with passenger and freight service improvements.
Industry stakeholders are expected to welcome the deal as a substantial opportunity, given the contract’s breadth and financial magnitude. As the rail sector continues to grapple with the demands of modernisation, decarbonisation and network capacity enhancement, this contract will play a pivotal role in shaping the railway’s operational backbone throughout the next decade.
